Item Limiter Fixed

The quarry limit fix had a weird side effect on some other blocks where it ignored data values, so the limit for one block ended up being shared between all blocks with that ID, so for example the limit for block 126:0 was shared between relays, collectors, plus RM & DM blocks and furnaces, giving a very low limit for each item!

This is now fixed and the limits behave as normal, what's more I managed to fix it without rolling back the quarry fix so the item limiter is now working exactly as originally intended.

Enjoy!
